In other words, Access Control Data (ACD) #1 includes special messages and common information related to "function i," and access control information (ACD) #2 includes specific information and common information related to skill 2 Access Control Data (ACD) #3 includes specific information and common information related to "Function 3".

For example, "Function 1" is a function that can be recognized by the drive system, and "Function 2, and "Function 3" are functions that cannot be recognized by the drive system. Access Control Data (ACD) #1 5〇〇 includes common information 510 and specific information 520. The common information 510 includes: an access control data identifier (aCD_ID) 511, which is an identifier for identifying an access control data (ACD); defect management area (DMA) recordability information 512 Indicates whether or not data can be recorded in the area 15 1332203 17789pif.doc other than the disc definition structure (ddS) 410 in the defect management area (DMA) 114; the spare area recordability information 513 indicating whether or not the spare areas 121 and 123 are available Recording data; and user data area recordable/renewable information 514 indicating whether data recording or reproduction can be performed on the user data area 122. 'The drive system can be determined by checking the access control data identifier (ACD still) 511. Access Control Data (ACD) #1 500 is about identifiable functions or about unrecognizable functions. That is, if the Access Control Data Identifier (ACDJD) 511 is the knowledge of the drive system. If there is no match, then the access control data (ACD) #1 500 is a function that can be recognized by the drive system; if the access control data identifier (ACD_ID) 511 is an identifier that the drive system does not recognize, then access Control Data (ACD) #1 5〇〇 is a function that cannot be recognized by this driver. Even if the drive system does not recognize the access control data identifier (ACD is still 511, the drive system can still be read and stored. The operation of the function that is not recognized by the drive system is correctly performed in the content of the common information 51. The specific information 520 includes access control information (ACD) #1 5〇〇的功鲁能 related information 52 卜 function related information 521 includes Setting information (such as a user, file system drive, scheduled recording/reproduction application, drive manufacturer, or an instruction set) that is set to optimally use access control data (ACD) #1 5〇〇 Function. Since the type, size or quantity of the function related information 521 is based on the function, the information column of the function related information 521 may not always have the same size, which is different from the total Information bar. ' VIII. A recording/reproducing device that can recognize a predetermined function sets the relevant information of this predetermined function in the manner in which the specific information of the function related 1332203 17789pif.doc access control data (ACD) is expected. The corresponding information corresponding to the setting information or corresponding to the setting information is set as a part or all of the common information. Then, although the recording/reproducing device which cannot recognize the predetermined function cannot recognize the specific information of the access control data (ACD) 'But this device can obtain the corresponding information from the common information, which is determined by the specific information, so the device can obtain the corresponding information, so that the media corresponding to this function can perform the operation correctly even if the function cannot be recognized. That is to say, the access control information (ACD) regarding the predetermined function includes specific information and common information, wherein the specific information is set such that the recording/reproducing device of the predetermined function performs the operation on the predetermined function. And the common information is set such that the recording/reproducing device that cannot recognize the predetermined function performs an operation corresponding to the predetermined function. When a medium is initialized/re-initialized or when each function is used, an access control profile (ACD) according to this function is recorded on the medium' or only for functions recognizable by the recording/reproducing device. • The diagrams in Figures 6A and 6B show the setting information included in the ACD when the predetermined function is the write protection function. The write protection function prohibits the function of recording data to certain areas of a medium, the entire area of the medium, or the user data area. Figure 6A illustrates a situation in which write protection access control data (ACD) 600 is set to a write protected state in accordance with an embodiment of the present invention. A recording/reproducing device that recognizes the write protection function can use the medium by applying a write protection function to a medium. When the user expects to set the user profile area of the media to the write protection state, the recording/reproducing device that recognizes the write protection function writes the protection access control data (ACD#1) 600 specific Write protection flag 621 in information 620

It is set to the write protection state as shown in Figure 6A. Further, for the recording/reproducing apparatus which does not recognize the write protection function, the recording/reproducing apparatus which recognizes the write protection function writes the record of the user data area of the common information 610 written to the protected access control data (ACD) 6 Relevant information barriers [such as defect management area (DMA) (except disc definition structure (DDS)) recordability information 612], spare area readability | message 613, and user (four) area recordability information 614 at least one of Set to unrecordable state, as shown in Figure 6A. In the information storage medium that performs defect management by the drive system, if the bedding material is made to the defect, the spare area is designated as the - replacement area, and the designated - defect (four) area (DMA) is stored. Defect management information without the replacement status and information about the disc record and the specified-disc collection structure (10)S). Therefore, the user data area is written in the defect management area (DMA) and the spare area is written.

When the status information of the i-second data (acd) is stored in the =疋(Y) structure (10)S), the dish-receiving structure (10) is included in the missing time zone (A). That is to say, if the disc is written to the protection state, the update of the access control data UCD) causes the meaning structure (10) S) of the information. If the status information of the record access control data ^ is not stored in the disc receiving structure (10) s),

In addition to the Disc Definition Structure (DDS), the defect management area is simply used (DMA 1332203 17789pif.doc recordability information. For write-write information storage media, the defect management area (DMA) corresponds to temporary defect management. The temperary defect management area (TDMA), the disc definition structure (DOS) corresponds to a temporary disk definition structure (TDDS). FIG. 6B illustrates write protection according to an embodiment of the present invention. The access control data (ACD) 600 is set to the write protection release state. When the user is expected to release the write protection state of the medium, the recording/reproducing device that recognizes the write/protect function writes the write access control The write protection flag 621 of the specific information 620 of the data (ACD) 600 is set to the write protection release state as shown in FIG. 6B. Further, for the unrecognizable recording/reproducing device of the write protection function, the write can be recognized. The recording/reproducing device of the protection function writes the relevant information column of the user data area of the common information 610 written in the protection access control data (ACD). The trap management area (dma) (except the disc definition structure (DDS)) recordability information 612], the spare area recordability information 613, and the user data area recordability information Lu 614 to the evening one of δ is The recordable state is as shown in the figure. By performing this process, even if the media is loaded into the recording/reproducing device of the unrecognizable write protection function in the future, the locked data can still be accessed by checking the write protection ( ACD) 600 Common Information 610 Technology gives this media the protection function to use this media. In other words, if the write protection status is set, the defect management area (DMA) (except the disc definition structure (DDS)) ), the spare area, and the user data area are set to the unrecordable state; if the write protection 1332203 17789pif.doc is released, the defect management area (DMA) (except the disc definition structure (DDS)), the spare area, And the user data area is set to a recordable state. By performing this process, the recording/reproducing device that does not recognize the write protection function can also use the write protection access control data according to the original purpose ( The media of ACD) thus increases the usage rate of the media. The graphics in Figures 7A and 7B show the setting information included in the access control data (ACD) when the predetermined function is the read protection function. The read protection function prohibits a medium. The function of certain areas, the entire area of the medium, or the data in the user data area is reproduced. Next, FIG. 7A illustrates that the read protection access control lean (ACD) 700 is set to be in accordance with an embodiment of the present invention. Read the status of the protection status. The recording/reproducing device with the read protection function can be set to read by the user data area of the media: the recording/regeneration step of the second protection function is deactivated and the read protection flag in the reading box 丄It 720 is determined.
